SHEET-REGISTERING MECHANISM. I

Application filed May 1, 1913.

To all whom it fiiay concern:

Be it known that LVFRANK L. Cnoss, a citizen of the United States,residing at Port-Washington, in the county of Queens and State of'Ne'wYork, have invented cer-' tain new and useful Improvements in'Sheet-Registering Mechanisms; and I do hereby declare the following to be afull, clear, and exact description of the'invention, suchas will enableothers skilled in the art to which j it 'apperta'ins to make and use thesame.

This invention relates to paper feeding machines and more particularlyto the sheet registering mechanism-of such machines.

The ,object of the invention is to provide novel and improved mechanismfor securing the accurate registering of the sheets in feeding themachines in which two sheets are fed side by-side to the front gages ofa printing press or othermachine for acting on the sheets;' to providenovel and improved devices for sheets against the front gages which maybe used in either two sheet or singlesheet feeding mechanisms;

tions of parts hereinafter illustrated therein.

" crating cams;

to provide novel a'nd improved means for securing the accurate registerof one edge of automatically fed sheets against two spaced gagesg and tootherwise improve the construction and mode of'opera ion of the sheetregistering mechanism of paper feeding machines.

To these ends the-invention consists in the features of construction andcombinadescribed and re ferred to in the claims. I

The various features-of the invention will be readilyunderstood from aninspection of the accompanying drawings and the.follo w- 1 'ing detaileddescription of the mechanism I In the drawings: Figure 1 is a sideelevation of so much of asheetfeeding' mechanism as is necessary toillustrate the application-of the present improvements thereto; Figs. 2and 2 are a plan view of the registering devicesillustrated in Fig. 1;Fig. 3 is a detail elevation showing'one of the op Fig. 4 is a sideelevation devices which are arranged d1.--

trated as embodied in-a paper feeding ma- 'chine adapted togforw'ard twosheets side by side to the front. gages of a printing press. The devices.for' separating individgages of the printing'press; Fig. 6 1s a 10 is asectional detail ,on

,ual sheets from two piles or banks arranged not shown, but may consistof combing'wheelsand sh'eet controlled cutouts such as are fuilyillustrated in the patent to Cross, No. 8,152,260, February 13, 1906.The sheets are advanced by the combing wheels into, position between thedelivery rolls 1' and the drop rolls 2-and are advanced over the.supporting bars 8 and supporting tongues 4 by the; delivery rolls 1 andtheir cooperating drop'rolls 2, and by the forwarding rolls 5 and thecooperating;

drop rolls 6. The drop rolls 2 are raised and lowered'in the usualmanner by a cam (not shown) secured to the constantly run- '-ning camshaft 7, and the drop rolls 6 are raised and lowered by a cam on theshaft engaging one end of a lever, the other end of arm on the drop rollshaftll, the. construcwhich engages-a rod 10 connected with antion'being similar to that shown in'Fig. 3.

The delivery rolls'l are driven by the usual mechanism similar to thatshown in the above patent and V driven in unison with the delivery rollsthrough a chain '12 which passes over a vance the sheets vto auxiliaryfront gages which are arranged somewhat back of the preventtheengagement of the front edges of the sheets with the front gages."After the sheets have been thus forwarded and arrestthe. forwardingrolls 5 are wheel on the forwarding roll shaft 18, Fig.2. i

The delivery and forwarding rolls'qadprinting press and I 60' theinvention is ill used they are acted upon by side registeringdevices'which bring the side edges of the sheets into registeragainsttwo side gages,

after which thesheets are advanced into base plate 16 and so arrangedthat the jaws 17 and 18 of the reciprocating gripper may ;.pass betweenthe adjacent ends of the blocks (Figs 7 to 10). The base 16' is slottedto receive the two lower jaws 7 of the gripper and is provided with aguideway for the I gripper carrying slide19. The upper. jaws lower endof the latch lever is arranged to 30 engage one or the other of two lugs27 and '18'of the grlpper comprisetwo thin fingers pivoted to anarm 20which is mountedupon a pivot stud 21projecting-from a standard 22 onthegripper slide. The arm 20 is forced in a direction to close the gripperjaws 18 against the sheet by a spring 23.

The opening and closingof the gripper is controlled by a latch lever '24pivoted to the standard 22- and provided with a roll v arranged teengage-a recess 26in the rearwa'rdly projecting end of the arm'20. The

' 2-8 which are secured upon the base plate 16.

Whenthe gripper carrying slide is advanced the jaws 18 are held inraisedposition,as indicated in Fig. 8. As the gripper completes itsforward movement the lower end of the lever 24 strikes the lug 28 anddisengages the roll 25 from the recess 26 so that the v jaws 18 of thegripper are forced against the sheet and form two transverse creases inits edge, as indicated in Fig. 10. The gripper slide is then retractedand the-gripper .jaws act to draw the edge of' the sheet against thefixedgage blocks 15. When the edge of the sheet strikes the gage thelateral movement of'thesheet is arrested and the gripper jaW'stslidelaterally along the sheet until the lower end of the latch lever 24strikes the lug 27 Continued movement of the gripper slide then forcesthe latch lever toward the left and the roll 25 rides up the inclinedend of the arm 20, raising the arm and lifting the gripper jaws 18 intothe position indicated in Fig. 8. If the edge of the sheet strikes onegage 15 before it does the other, the gripper engaging that part of theedge which has not been brought against the corresponding gage 15continues to draw the edge of the sheet toward the gage until. the thegage. At the same time theother gripper is slidedge at this point isarrested by ing over the sheet and continuing to draw the edge at thispoint against the other age 15', thus insuring the accurate register 0the edge against the two spaced gages.

The base plate 16 is provided with a hub which surrounds a transverselyarranged supporting rod 29. and the base plate may be readily adjustedon-ethe rod by a pinion 30 .,mounted on the base plate and engagingraclrteeth formed on the rod. The p'inion is formed on a sleeve 31moun'ted in a split boss 32 and provided with a knurled head 33. Thebase plate may be. secured in adjusted position by a clamping bolt 34which passes through the sleeve 31 and is provided with a head engagingthe lower section of to the end of the-clamping bolt and serves to-forcethe head of the bolt against the lower sideof the split boss, and aflange 36 on the sleeve 31 against the upper side of the split boss, asindicated in Fig. 7.

The base plate is held from rotation on the rod 29 by a guiding lug 37which surrounds a rod 38. The rod 383s mounted to move longitudinally inthe supporting brackets 39 and.40 and carries a collar 41 provided witha laterally projecting arm 42 arranged to fit between lugs 43 on thegripper carryin slide'19. The collar 41 is split,

.as indicate in Fig. 7, and may beclamped in adjusted position on therod 38 by a clamping bolt 44. When the side register devices are to' beadjusted transversely of the machine the clamping bolt 44 is loosened sothat the collar 41 may slide on the rod 38.

'Ifthe registering devices are to be thrown out of action the bolt 44may be loosened and the collar 41 swung about the rod.38 to disengagethe arm 42 from the lugs 43.

The rods 38 by which the side registering grippers are reciprocated areso connected that the side registering grippers at the opposite sides ofthe machine move inward and outward in unison. As shown, the inner ends,of the rods 38 are provided with 001- lars 38 which have slidingengagement with the rods 29 and are connected by links 45 with theopposite ends of levers 46, the collars 38 at one side of the machineare con- 'the boss 32. A knurled nut 35 is screwed on I nected'to bellcrank levers 47 and 48by links .45. The bell crank lever 47 is connectedby .a link'49 with one arm of a lever 50, the other arm of which carriesa roll engaging a'cam 51 secured to the cam shaft 7. The link 49 is alsoconnected through a link 52 with the lever 48 so that the levers 47 and-48 are moved in unison.

Each of the auxiliary front gages for positioning the front edge of thesheets preparatory to theoperation of the side registering devicescomprises gage fingers 53 formed on the end of a lever 5-1 and arrangedto straddle a' thin metal tongue which one end of The lever 54 androlls'60- are alternately of the sheets. The lever is forced in adirection. to hold the gage fingers 53- in the path of the sheet by aspring 58 and the position of the fingers i sdetermined by a stop screw59 against which the rear end ,of, the lever is held by the spring. Thegage fingers 53 are arranged a short distance back of the front gages 14and are held in, the path of the sheets asthey are advanced by theforwarding rolls so that the advance-of the sheet is arrested" beforeits front edge reaches the front gages 1f After'orduningjthe time thatthe side registering devices 1 are drawing the edges of the sheetsagainst the side gages the levers 54 areraised to withdraw the gagefingers 53 from the path of the sheet, and after the side register ofthe sheet has been completed the sheet ismoved forward against the frontgages by devices which grip the front edge of the sheet and draw thesheet forward so that accurate side and front register of the sheet isinsured.

The devices'for gripping and drawing the sheet forward against. thefront gages 14 comprise rolls 60 adapted to press the sheets against thetongues When the auxiliary front gages 53 are raised, and means for. ad-

vancing: the tongues 55 While the sheets are engaged by the .rolls sothat the sheets gripped between the rolls andtongues are carried forwardwith the tongues until the" front edges of the sheets strikethe frontgages, after which the tongues may slide along the under surface ofthesheets. In the construction shown, each roll i's'carried' upon an arm61 pivotally mounted upon a stud 62 projecting from the lever 54.

The arm 61 is forced in a directionto en- 4 gage the roll withIthetongue 55 by a torsional spring 63, the tension of which may beadjusted by adjusting the collar 64 to the spring is 'attached.

raised and lowered through a rock shaft 65 to which a lever 66 issecured, One end of the lever isconnected by a link 67 with the T lever54 and theotherarm of the'lever 66 is connected by a link 68 with theroll carrying arm 61. The upper end of. the link 68 is a connected withthe. lever 66 by a pin and slot connection so that the roll 60 may .befree to move with relation to the arm 66 and its pressure upon the sheetwill, therefore, de pend upon the spring 63. The rockshaft 65 isoperated at-properinterv'als' fromla cam 69 secured to the cam shaft 7and engag ing one end of a lever 70, the other end of whichis connectedby a link 71 to an arm 72 on the rock shaft.

The tongue 55 is mounted to slide in a support 73 secured to atransverserod 74 and is reciprocated from a rock shaft ,75

through an arm 76 secured to the shaft and.

'- tering devices, andthese sheets which usually have comparatively longside edges and comparatively sh'ort front edges may be quicklyandaccurately registered against thefiside gages before their front edgesare brought against the front gages and then drawn forward -intoaccurate register against the front gages without disturbing the sideregister.

The same machine ,may also be used to feed single sheets "to the frontgages. In such "case all but one of the side'registering devices willbedisconnected or thrown out ofa'ction, two of thecomber rolls and cut--outs will be thrown out of action, the auxili'ary front gages will berendered inactive, and the timingof the side registering devices Withrelationto thedevices for ad "ancing the sheets against therfront gageswill-be changed by changingor adjusting the cams for-operating the sideregistering devices and for'depress'ing the rolls 60 andadvancing thetongues 55. In this case the rolls 60 will be depressed and the tongues55 advanced to draw the front edge of the sheet into accurate registeragainst the two spaced front gages 141 before the side registeringdevice acts to draw the sheet lat erally against the side gage. In thiscase either roll and tongue will'continue to draw the edgeof the sheetagainst the corresponding gage after the edge at that point has beenarrested, and while the other roll and tongue are drawing the edgeagainst the other front gage, in case 'theedge is out'of alinement whenadvanced into position between the rolls and tongues. v
